摘要: 为构建狐尾藻(Myriophyllum verticillatum L.)处理畜禽养殖污水植物工厂治污工艺,研究了人工气候环境下不同光质处理对狐尾藻生长和畜禽养殖污水净化效果的影响。结果表明,红蓝光3∶1处理下狐尾藻生物量、净化效率显著高于红蓝光5∶1处理、白光处理,与自然光照(CK)之间差异不显著。红蓝光3∶1处理、红蓝光5∶1处理叶绿素a、叶绿素b和叶绿素总量与自然光照之间差异不显著,而与白光处理之间差异显著。红蓝光3∶1处理在生物量、净化效率和光合色素含量上与自然光照相当,是适宜狐尾藻生长的人工光源。

Abstract: In order to construct plant factory technology for Myriophyllum verticillatum L. treatment of livestock and poultry farm wastewater, the effects of different light quality on the growth characteristics of Myriophyllum verticillatum L. and purification capacity of livestock and poultry farm wastewater were investigated. The results showed that the biomass and purification efficiency were significantly higher under the treatment of red and blue light 3∶1 than that under the treatment of red and blue light 5∶1 and white light, with no significant difference with natural light (CK). The content of chlorophyll a, chlorophyll b and total chlorophyll under the treatment of red and blue light 3∶1 and 5∶1 were not significant compared with CK, but significant compared with the treatment of white light. The treatment of red and blue light 3∶1 was similar to natural light in biomass, purification efficiency and photosynthetic pigment content, and it was suitable for the growth of Myriophyllum verticillatum L..

Key words: Myriophyllum verticillatum L., LED, light qualities, growth, purification efficiency
